Flying doughnut terahertz pulses generated from semiconductor currents
Kamalesh Jana, Yonghao Mi, Søren H. Møller +5
The ability to manipulate the space-time structure of light waves diversifies light-matter interaction and light-driven applications. Conventionally, metasurfaces are employed to l…
Mapping the direction of electron ionization to phase delay between VUV and IR laser pulses
M. Mountney, G. P. Katsoulis, S. H. Møller +3
We theoretically demonstrate a one-to-one mapping between the direction of electron ionization and the phase delay between a linearly polarized VUV and a circular IR laser pulse. T…
Few-femtosecond resolved imaging of laser-driven nanoplasma expansion
C. Peltz, J. A. Powell, P. Rupp +23
The free expansion of a planar plasma surface is a fundamental non-equilibrium process relevant for various fields but as-yet experimentally still difficult to capture. The signifi…
Strongly enhanced upconversion in trivalent erbium ions by tailored gold nanostructures: toward high-efficient silicon-based photovoltaics
Jeppe Christiansen, Joakim Vester-Petersen, Søren Roesgaard +6
Upconversion of sub-band-gap photons constitutes a promising way for improving the efficiency of silicon-based solar cells beyond the Shockley-Queisser limit. 1500 to 980 nm upconv…
